Describe what might happen to an amino group or a carboxyl group of an amino acid, if that amino acid is placed into water.

Answers

Answer:

Amino acids are the monomers that makeup proteins. This amino acid is unionized, but if it were placed in water at pH 7, its amino group would pick up another hydrogen and a positive charge, and the hydroxyl in its carboxyl group would lose and hydrogen and gain a negative charge.

Explanation:

Each amino acid has the same fundamental structure, which consists of a central carbon atom, also known as the alpha (α) carbon, bonded to an amino group (NH2), a carboxyl group (COOH), and to a hydrogen atom. In the aqueous environment of the cell, both the amino group and the carboxyl group are ionized under physiological conditions, and so have the structures -NH3+ and -COO–, respectively. Every amino acid also has another atom or group of atoms bonded to the central atom known as the R group. This R group, or side chain, gives each amino acid protein-specific characteristics, including size, polarity, and pH.

Calculator

Answers

Answer:

Multicellular

Explanation: used quizziz

Of the options listed, "They are prokaryotic" and "They are not multicellular" are characteristics that both blue-green algae and bacteria share.

What are blue green algae?

Blue-green algae, also known as cyanobacteria, are a type of bacteria that are capable of performing photosynthesis. This makes them unique among bacteria, as most other bacteria do not have the ability to produce their own food in this way. As a result, blue-green algae play an important role in the carbon cycle and contribute to the production of oxygen in the Earth's atmosphere.

Blue-green algae can be found in a variety of environments, including fresh and salt water, soil, and rocks. Some species are free-floating, while others form colonies or filaments. In certain conditions, such as nutrient-rich water or high temperatures, blue-green algae can grow rapidly and form blooms, which can have negative impacts on aquatic ecosystems and human health.

Despite their classification as bacteria, blue-green algae have a number of characteristics that are more similar to algae than to other bacteria, which is why they are sometimes referred to as "blue-green algae."

The energy that organisms use for supporting life processes such as movement and reproduction are released into the ecosystem as what type of energy?(1 point)

chemical

heat

radiant

nuclear

Answers

Question: "The energy that organisms use for supporting life processes such as movement and reproduction are released into the ecosystem as what type of energy?"

Answer: "Heat energy is used by organisms for supporting life processes, including movement and reproduction. Hence, Option B is the correct choice."

Heat energy is the degree of internal energy contained in an organism and is released into the ecosystem.

What is heat energy?

Heat energy is what generates the internal and random movement of the particles of a body.

Characteristics of heat energy

Organisms constantly release heat energy.

This energy is renewed through the consumption of food, which contains the calories that allow us to continue emitting that energy as long as we live.

Therefore, we can conclude that the temperature of an organism and its ability to generate life processes such as movement depend on its heat energy.

how does the cell cycle aid the conservation of genetic information

Answers

Explanation:

The cell cycle aids in the conservation of genetic properties by the first stage which replicates DNA from the cell or Anaphase.

Cell cycle aid the conservation of genetic information through the use of either a positive feedback mechanism or a negative feedback mechanism.

A cell cycle can be defined as an ordered sequence of events that takes place within a living cell as it grows and divide into two (2) daughter cells.

Basically, a cell cycle is made up of four (4) distinct stages and these include:

Gap 1 (G1).Synthesis (S).Gap 2 (G2).Mitosis (M).

A genetic information refers to the heritable biological information that are typically stored in the base sequence of an organism's deoxyribonucleic acid (DNA) or ribonucleic acid (RNA) in certain viruses, according to their genetic code.

Generally, living cells communicate with one another by generating, transmitting, receiving and responding to chemical signals within the body of a living organism.

On a related note, cell communication is not completely perfect and as such causes genetic variation.

However, cell cycle aid the conservation of genetic information through the use of either a positive feedback mechanism or a negative feedback mechanism.

Hence, living organisms are able to transfer their genetic information from one generation to another based on the actions of cell cycle.

what is a ecosystem? write 2 to 5 sentences to explain it​

Answers


Ecosystem is that it is a community or group of living organisms that live in and interact with each other in a specific environment.

For instance, tropical forests are ecosystems made up of living beings such as trees, plants, animals, insects and micro-organisms that are in constant interaction between themselves and that are affected by other physical (sun, temperature) or chemical (oxygen or nutrients) components.


An ecosystem consists of a community of organisms together with their physical environment.
Ecosystems can be of different sizes and can be marine, aquatic, or terrestrial. Broad categories of terrestrial ecosystems are called biomes.
In ecosystems, both matter and energy are conserved. Energy flows through the system—usually from light to heat—while matter is recycled.
Ecosystems with higher biodiversity tend to be more stable with greater resistance and resilience in the face of disturbances, or disruptive events.
